Aren't lichens & mushrooms opportunistic, i.e. don't they grow on diseased
and decaying wood?

Lichens are epiphitic multi-organisms. The fungal component obtains its
nutrients largely from filtering rainfall & from atmospheric impurities &
from bugshit, not from decaying wood. The algal component performs
photosynthesis & obtains nutrients from light, plus it too benefits from
bugshit. They are completley harmless to their hosts & can even be
benificial.

Those are lichens (pronounced "liken"). They do no harm to your trees and
shrubs whatsoever.

If something is killing your trees, it is something else.

If you still insist upon removing them, spray your plants with diluted
liquid chlorine bleach.

I have encrustations on several small trees and bushes and wonder if
anyone might identify them and advise on how to get rid of them.
Pictures are on the following web site:

Many thanks in anticipation,
